Application tilezl November 13, l8r3. Serial No. 111.688. (No modal.)

T0 (b/ Z whom it nmz concern:

Be it known that I, Jaoon .Lioons, of Xew York city, in the county ofNew York, and in the State of New York, have invented certain new anduseful Improvements in Illuminating i ilcsz and I do herebydeclare thatthe following is a full. clear, and exact description thereof, referencebeing bad to the accompany ing drawings, making a part of thisspecification, in which- Figure 1 is a perspective view from the lowerside of one of the plain lensesemployed by me. Fig.2 is a plan view fromabove oi a portion of the metal tile in which the same is set, and Fig.3 is a vertical section of said tile fully glazed and combined withanother similar tile.

Letters of like name and kind refer to like parts in each of thefigures.

My invention is intended to obviate certain defects which sometimesexistin illuminatingtilcs, and to lessen the liability to injury causedby shipment of the same; and it consists, principally, in anilluminating-tile provided with elongated light openings, in combinationwith lenses which are correspondingly elongated, and within theirperipheries are -each provided with a circumferentiali 5 joints formedby the plastic material possess groove that corresponds to and isadapted to embrace the flange which forms the bottom of the lensrecess,substantially as and for the purpose hereinafter specified.

It consists, further, in an illuminating-tile provided upon or withinits edge with arib or a groove which may be caused to fit within or overthe corresponding groove or rib of a contiguous tile, in combinationwith cement placed between such engaging edges, and with bolts whichpass through the lower portions of each tile and through thesupporting-frame, substantially as and for the purpose hereinaftershown.

In the annexed drawings, A represents my improved tile, which consistsof a metal plate having its upper face recessed, and provided withinsuch recess with a series of light-openings, a, that have any desiredrelative arrangement and are each surrounded by a curb, a, that extends,preferably, about one-half the distance between the bottom of saidrecess and the upper surface of said tile.

Each light-openinga is somewhat elongated,

and within the same is fitted a glass lens, B, that is correspondinglyshaped and has such sire as to enable its lower end to be easily passedinto the same. Near its lower end each of said lenses is provided with acircumferential groove, 3), which'has such vertical dimensions as toenable it to contain the flange of that forms the edge of saidlight-opening, and has such depth as to permit said lens, alterinsertion within said opening, to be turned until its longest diameteris in a line with the shortest diameter of the latter, in which positionsaid lens is securely locked by the engagement of said groove with saidflange.

Before placing the lens B in position, its groove 1) is filled withplastic cement, which, by the turning of said lens within its opening,is caused to closely fill the space between the flange c and groove 1),the surplus material being pressed outward and removed. After all ofsaid lenses are in position the spaces between their peripheries arefilled with said plastic cement C, and the upper surface of the same,while soft, covered with powdered flint, in order to afford a firmfoot-hold.

Lenses thus secured within a tile are not liable to be loosened whilethe latter is being transported to or placed in position, while the fargreater durability and are more certain to be water-tight than are thoseproduced by any of the usual methods.

In order that tight joints may be secured between the edges ofcontiguous tiles, I provide each tile A at such point with a rib, a, orgroove to, which extends horizontally along its edge, and when said tileis in place, passes into or over the corresponding groove a or rib a ofthe adjacent tile. Plastic cement O is placed between the edges of saidtiles before or aft-er the same are combined, so as to closely fill thespace and produce a tight joint at such point.

The tiles A are each firmly secured to the supporting-frame l) by meansof bolts E,whieh pass through said parts, as shown in Fig. 3. Enid boltsare preferably placed in position within said tile before the spacesaround the lenses are filled with cement C, but may, if desired, beinserted at any time by leaving suitable openings and afterward fillingthe same with cement,so as to cover the bolt-head.

I OO

The joint thus produced possesses great strength and durability, and isnot liable to leak under any ordinary usage.

Having thus fully set forth the nature and merits of my invention, whatI claim as new 1s- 1. The lens for illuminating-tiles, having its lowerportion elongated diametrically and provided with a circumferentialgroove, substantially as and for the purpose specified.

2. In combination with the lens-supporting portion of anilluminating-tile provided with an elongated lensopening, the lenshaving its lower portion correspondingly shaped and adapted to be passedthrough the lens-opening, and having a circumferential groove adapted toallow the lens to be turned after its lower portion has been passedthrough the opening, all substantially as and for the purpose shown.

3. In combination with alens-support of an illuminating-tile providedwith one or more elongated openings. one or morelenses having theirlower portions shaped to correspond with such openings and provided withcircumferential grooves adapted to allow the lenses to be turned in theopenings to bring their longest diameters at right angles to the longestdiameters of the openings, and a body of cement surrounding the lenses,substantially as and for the purpose described.

4. In combination with the lenssupporting portion of the tile providedwith elongated openings, the lenses correspondingly shaped and groovedto receive the edges of the openings, turned to bring their longestdiameters at right angles to the longest diameters of the openings, andcement in the grooves in the lenses, substantially as and for thepurpose specified.

5. In combination with the lens-support of an illuminating-tile providedwith an elongated lensopening, the lens correspondingly shaped andhaving the cylindrical neck adapted to allow the lens to be rotated inthe opening to bring the longer diameter of the lens across the opening,substantially as and for the purpose described.

6. In combination with asupporting-frame, an illuminatingtile having inits edge a groove and an illuminating-tile having in its edge a ribentering the groove in the other tile, cement placed between theengaging edges of the tiles, and bolts passing through the lowerportions of the tiles and portions of the supporting-frame,substantially as and for the purpose described. 7

In testimony that I claim the foregoing I have hereunto set my hand this8th day of November, A. D. 1883.
